When memory fails, intuition reigns: midazolam enhances implicit inference in humans

People often make logically sound decisions using explicit reasoning strategies, but sometimes it pays to rely on more implicit "gut-level" intuition. The transitive inference paradigm has been widely used as a test of explicit logical reasoning in animals and humans, but it can also be solved in a more implicit manner. Some researchers have argued that the hippocampus supports relational memories required for making logical inferences. Here we show that the benzodiazepene midazolam, which inactivates the hippocampus, causes profound explicit memory deficits in healthy participants, but enhances their ability in making implicit transitive inferences. These results are consistent with neurocomputational models of the basal ganglia-dopamine system that learn to make decisions through positive and negative reinforcement. We suggest that disengaging the hippocampal explicit memory system can be advantageous for this more implicit form of learning.     

Walter Miles, Pop Warner, B. C. Graves, and the psychology of football

In 1926-1927, a graduate student, B. C. Graves, working with Stanford University psychologist Walter Miles and legendary football coach Pop Warner, conducted an investigation of variations in signal calling as they affected the charging times of football players. The study was one of two that involved Miles and the ingenious multiple chronograph that he had invented to time the reactions of seven players simultaneously. These studies represented a brief digression in the career of Miles, who certainly was no sport psychologist. They tell of an interesting collaboration between scientist and coaches that produced one of the richest studies in sport psychology in the first half of the twentieth century.     

Religious Practices Among Islamic Immigrants: Moroccan and Turkish Men in Belgium

This study examines the religious participation of Islamic immigrants in Belgium using data from the Migration History and Social Mobility Survey collected in 1994–1996 from 2,200 men who had immigrated from Turkey and Morocco. Religious participation is measured as mosque attendance, fasting during Ramadan, and sacrificing a sheep at the Festival of Sacrifice. Results show that the religious participation of Islamic immigrants depends on both premigration and postmigration characteristics. Religious participation is higher among immigrants who: (1) attended a Koranic school in their country of origin, (2) were socialized in a religious region of their home country, (3) received little schooling, (4) currently live in an area of Belgium with a greater number of mosques, and (5) associate with a high number of co‐ethnics. These results suggest that the religious participation of Islamic immigrants in Belgium is an outcome of characteristics unique to immigrants as well as processes common among the general population.     

Some Contributions of Empirical Infant Research to Adult Psychoanalysis: What Have We Learned? How Can We Apply It?

The direct links among early development, a model of the mind, and the content of the transference are challenged from two vantage points—empirical infant research and motivational systems theory. A discussion of these contributions and of their application in two case vignettes suggests a new view of therapeutic change—a view involving (a) recognition of the coconstruction of the analytic relationship, (b) contributions of self- and interactive regulations, of their disruption and repair, and of heightened affective moments to the ongoing analyst-patient interchange, (c) emphasis on the analyst's recognition of the patient's communications as developmental strivings, (d) tracking of sequences of disruption and repair, and (e) dialectic between repetition and transformation. These various interactions develop in a patient new expectations of being understood, of being understandable, and of participating in a dialogue that does not, for example, require bolstering the other or sacrificing oneself to the other. These new expectations lead to new themes as well as to the transformation of old themes that organize experience.     

Locus of Control,Machiavellianism, and Managerial Job Performance

In this study, we examined the moderating effect of locus of control on the relationship between Machiavellianism and job performance of store managers in a retail setting. Our results indicated a significant moderating effect for managers who perceive that they have an external control orientation but not for managers with an internal control orientation.
